Description

  The present invention relates to a mixing element, a mixing device, a mixing method, a stirring blade, a stirring device, and a stirring method, and relates to a technique used in the field for processing fluid mixing, fragmentation, emulsification, and the like. Used for both dynamic and static mixing.

  As a device for mixing fluid, a dynamic mixing device widely used is a device in which a stirring blade is disposed in a fluid in a stirring tank and the stirring blade is rotated to perform mixing. On the other hand, static mixers are widely used as static mixing devices. Such static mixing devices generally have no moving parts and are therefore widely used in fields where fluids need to be mixed in a line, such as in the chemical and food industries.

Patent Document 1 is an example of a static fluid mixing device. This fluid mixing device is formed by concentrically superposing two large and small discs formed by arranging a number of polygonal chambers open on the front surface in a honeycomb shape, with a through hole formed in the center. It consists of a diversion unit. The chambers of the large-diameter disk and the chambers of the small-diameter disk are arranged in different positions so that the chambers communicate with other chambers facing each other, and the plurality of flow guiding units are superimposed. .
In the fluid mixing device, the fluid is mixed by being dispersed, inverted, and joined when moving through each chamber of the flow guiding unit, and further mixed by vortex, turbulence, collision, etc. in each chamber. . And it is what mixes by repeating re-dispersion and a gathering alternately radially from the center part to the outside or from the outside to the center part, and is characterized by obtaining a high mixing effect.

However, the fluid mixing device has a limited mixing effect because the flow path area through which the fluid flows is only the portion where the small chambers of the two large and small disks communicate. Further, when the flow rate of the fluid is large, there is a problem that the pressure loss of the entire apparatus becomes large and a large power is required.
In addition, there is a problem in maintenance that a fluid residue or a foreign substance adheres to the dead space of the small chamber and requires a lot of time for cleaning work.

  On the other hand, in order to mix the liquid in the stirring tank, turbine blades and the like are widely used, but there is a stirring blade of Patent Document 2 in order to increase mixing efficiency. This is because four sets of two agitators are installed on both sides of a support that is attached to the agitation shaft, with two partial agitators arranged in parallel with respect to the plane of rotation on each side. The outer opening of the stirrer is gradually retracted inward as it moves backward with respect to the rotation direction, so that a large degree of mixing can be obtained easily, reliably and with little power in a short time. It is done.

  However, even with the above-described stirring blade, the mixing efficiency is limited because the fluid is mixed only around the partial stirrer attached to the support.

  Further, in Patent Document 3, the flow guiding unit body of Patent Document 1 is disposed in the liquid in the stirring tank as a mixing rotator, but the fluid is mixed only in the vicinity of the mixing rotator. Therefore, the mixing efficiency is limited.

JP 58-133822 A JP-A-8-182924 JP 11-114396 A

The present invention has been made in view of the above, and has a high mixing effect in a small space as a mixing element, a mixing device, and a mixing method, and can mix a large amount of fluids, and a cleaning operation. It is an object to be able to easily perform.
Another object of the present invention is to provide a stirring blade, a stirring device, and a stirring method that have a high mixing effect in a small space and can easily perform a cleaning operation.

The present invention provides the following mixing element, mixing device, mixing method, stirring blade, stirring device, and stirring method in order to solve the above problems.
(1) Mixing element One configuration of the mixing element according to the present invention is:
A laminated body in which a plurality of laminated elements are laminated, and a first plate and a second plate arranged to face each other with the laminated body interposed therebetween,
The laminated element has a plurality of first through holes,
The second plate has a through hole communicating with at least one first through hole of the laminated element,
The laminated element is arranged so that a part or all of the first through holes partially overlap with the first through holes of the adjacent laminated elements, and the first through holes of the adjacent laminated elements It is arrange | positioned so that a fluid may be connected to the through-hole of 1 through so that a flow is possible in the direction where a lamination | stacking element is extended (1st technical means).

According to this configuration, the fluid that has flowed from the through hole of the second plate flows into the laminated body from the first through hole of the laminated element that communicates with the through hole of the second plate, and communicates inside the laminated body. Are mixed while flowing through the first through hole to flow out of the laminate.
At both ends in the stacking direction of the stacked body, the first through hole of the stacking element is closed in the stacking direction by the first plate and the second plate. Therefore, the fluid that has flowed into the laminated body is guided so as to flow through the first through hole that communicates in the extending direction of the laminated element.
Contrary to the above, even when the fluid flowing into the laminated body from the first through-hole of the laminated element flows out of the through-hole of the second plate, the fluid is communicated with the first through-hole inside the laminated body. Mixed while circulating.
Here, the extending direction of the laminated element means a direction perpendicular to the laminated direction of the laminated element.

  Furthermore, according to this configuration, the fluid flows out from the first through hole to the other first through hole communicating with the stacking direction, and conversely, the other first through hole communicating with the stacking direction. Since the inflow and outflow are repeated in the first through-hole communicating in a complicated manner by flowing into the first through-hole from the hole, the fluid flows more complicated and the mixing effect is increased. Moreover, since the cross-sectional area in the direction in which the laminated element through which the fluid flows increases by increasing the number of laminated laminated elements, a fluid having a larger flow rate can be mixed.

The composition of the mixing element according to another aspect of the present invention is:
In the mixing element according to the first technical means,
The plurality of laminated elements, the first plate, and the second plate are fixed so as to be disassembled (second technical means).

  According to this configuration, the mixing element is decomposed into each of the laminated elements, the first plate, and the second plate, thereby removing residues and foreign matters remaining in the first through holes of the laminated element. Cleaning operation can be facilitated.

The composition of the mixing element according to another aspect of the present invention is:
In the mixing element according to the first or second technical means,
The plurality of laminated elements, the first plate, and the second plate can be divided (third technical means).

  According to this configuration, the mixing elements can be easily arranged even in complicated shapes because each of the laminated elements, the first plate, and the second plate can be divided.

The composition of the mixing element according to another aspect of the present invention is:
In the mixing element according to the first to third technical means,
The laminated element is formed by drilling a metal plate having a plurality of through holes (fourth technical means).

  According to this configuration, it is possible to produce a large number of laminated elements in a short time by punching a metal plate such as a commercially available punching metal having a plurality of first through holes by punching or the like. Therefore, the mixing element can be manufactured at a low cost.

The composition of the mixing element according to another aspect of the present invention is:
In the mixing element according to any one of the first to fourth technical means,
The outer shape of the first plate is larger than the through hole of the second plate (fifth technical means).

  According to this structure, when a fluid passes a laminated body, it can suppress that it short-circuits in a lamination direction and flows. Therefore, the fluid that has flowed into the laminated body easily circulates in the direction in which the laminated elements extend, and therefore circulates through more communicating first through holes. Therefore, the fluid mixing efficiency can be improved.

The composition of the mixing element according to another aspect of the present invention is:
A laminated body in which a plurality of laminated elements are laminated, and a first plate and a second plate arranged to face each other with the laminated body interposed therebetween,
The laminated element has a plurality of first through holes,
The second plate has a through hole communicating with at least one first through hole of the laminated element,
The laminated element is arranged such that a part or all of the first through-hole communicates with a first through-hole of an adjacent laminated element so that fluid can flow in the direction in which the laminated element extends. And
The laminated element has a second through hole larger than the first through hole, and is arranged such that the second through hole communicates in the laminating direction to form a hollow portion in the laminated body. And
A through hole of the second plate is communicated with at least one first through hole of the laminated element through the hollow portion (sixth technical means).

According to this configuration, the fluid that has flowed from the through hole of the second plate flows into the hollow portion of the mixing element. Here, the hollow portion refers to a hollow space portion formed by laminating the second through holes of the laminated element. Since the flow resistance when the fluid flows in the hollow portion is small, the pressure distribution in the stacking direction is small. Therefore, regardless of the position in the stacking direction, the fluid flows into the stacked body through the first through holes that open to the inner surface of the hollow portion almost evenly and flows in the direction in which the stacking element extends.
Contrary to the above, even when the fluid that has flowed into the laminated body from the first through-hole of the laminated element flows out into the hollow portion, the fluid passes through the laminated body almost uniformly regardless of the position in the lamination direction. Flows out from the first through hole that opens from the inside of the laminated body to the inner side surface of the hollow portion.

(2) Mixing device One configuration of the mixing device according to the present invention is as follows.
A mixing element according to any one of the first to sixth technical means, and a casing having an inlet and an outlet for accommodating the mixing element,
The first plate of the mixing element has an outer shape smaller than the casing inner shape;
The second plate of the mixing element has an outer shape that is substantially the same as the inner shape of the casing, and the outer surface of the second plate is substantially inscribed with the inner surface of the casing. (Seventh technical means).

According to this configuration, the fluid flowing in from the inlet of the casing flows into the laminated body from the first through hole of the laminated element communicating with the through hole of the second plate via the through hole of the second plate. To do. And it mixes, distribute | circulating the 1st through-hole which connects the inside of a laminated body, flows out from a laminated body, and also flows out from a casing exit.
Contrary to the above, when the fluid inside the laminated body flows out from the through hole of the second plate, the fluid flows into the laminated body from the first through hole of the laminated element. And it mixes, distribute | circulating the 1st through-hole which connects inside a laminated body, flows out from the 1st through-hole connected with the through-hole of a 2nd board, and also flows out from a casing exit.

At both ends in the stacking direction of the stacked body, the first through hole of the stacking element is closed in the stacking direction by the first plate and the second plate. Therefore, the fluid that has flowed into the laminated body is guided so as to flow through the first through hole that communicates in the extending direction of the laminated element.
In addition, since the 1st board which comprises a mixing element has outer shape smaller than casing inner shape, it does not prevent that a fluid flows in into a laminated body. Further, since the outer surface of the second plate is substantially inscribed with the inner surface of the casing, the fluid can surely flow into the laminated body from the through hole of the second plate.
Here, the extending direction of the laminated element means a direction perpendicular to the laminated direction of the laminated element.

  Furthermore, according to this configuration, the fluid flows out from the first through hole to the other first through hole communicating with the stacking direction, and conversely, the other first through hole communicating with the stacking direction. Since the inflow and outflow are repeated in the first through-hole communicating in a complicated manner by flowing into the first through-hole from the hole, the fluid flows more complicated and the mixing effect is increased. Moreover, since the cross-sectional area in the direction in which the laminated element through which the fluid flows increases by increasing the number of laminated laminated elements, a fluid having a larger flow rate can be mixed.

  Furthermore, according to this structure, since a fluid can be mixed inside a casing, it can be used as an in-line static mixing device. Therefore, the fluid can be mixed continuously.

(3) Mixing method One configuration of the mixing method according to the present invention is:
A method of mixing fluid with a mixing device according to the seventh technical means,
The fluid that has flowed into the mixing element is caused to flow through the first through-hole in the direction in which the laminated element extends to flow out of the mixing element (eighth technical means).

According to this method, the fluid flows into the laminated body from at least one first through hole of the laminated element that communicates with the through hole of the second plate via the through hole of the second plate. And it mixes, distribute | circulating the 1st through-hole which connects the inside of a laminated body, flows out from a laminated body, and also flows out from a casing exit.
Contrary to the above, when the fluid inside the laminated body flows out from the through hole of the second plate, the fluid flows into the laminated body from the first through hole of the laminated element. And it mixes, distribute | circulating the 1st through-hole which connects inside a laminated body, flows out from the 1st through-hole connected with the through-hole of a 2nd board, and also flows out from a casing exit.

At both ends in the stacking direction of the stacked body, the first through-holes of the stacking element are closed in the stacking direction by the first plate and the second plate arranged to face each other. Therefore, the fluid that has flowed into the laminated body is guided so as to flow through the first through hole that communicates in the extending direction of the laminated element.
Since the first plate has an outer shape smaller than the inner shape of the casing, the fluid is not prevented from flowing into the laminated body. Further, since the outer surface of the second plate is substantially inscribed with the inner surface of the casing, the fluid can surely flow into the laminated body from the through hole of the second plate.
Here, the extending direction of the laminated element means a direction perpendicular to the laminated direction of the laminated element.

  Furthermore, according to this method, the fluid flows out from the first through hole to the other first through hole communicating in the stacking direction, and conversely, the other first through hole communicating in the stacking direction. Since the inflow and outflow are repeated in the first through-hole communicating in a complicated manner by flowing into the first through-hole from the hole, the fluid flows more complicated and the mixing effect is increased. Moreover, since the cross-sectional area in the direction in which the laminated element through which the fluid flows increases by increasing the number of laminated laminated elements, a fluid having a larger flow rate can be mixed.

  Furthermore, according to the present method, the fluid can be mixed inside the casing, so that it can be applied as an in-line static mixing device. Therefore, the fluid can be mixed continuously.

(4) Stirrer One configuration of the stirrer according to the present invention is as follows.
The mixing element according to the sixth technical means is attached to a rotating shaft that is rotationally driven, and the mixing element is disposed in the fluid in the stirring vessel (ninth technical means) .

According to this configuration, the mixing element is rotated by the rotation of the rotating shaft, the centrifugal force acts on the fluid inside the mixing element, and the fluid is mixed while flowing through the communicating first through hole. It discharges from the 1st through-hole opened to a side surface. The fluid inside the stirring tank is sucked into the hollow portion by the rotation of the mixing element, and flows into the laminated body through the first through hole that opens on the inner surface of the hollow portion. Thus, the fluid is mixed.
At both ends in the stacking direction of the stacked body, the first through hole of the stacking element is closed in the stacking direction by the first plate and the second plate. Therefore, the fluid that has flowed into the laminated body is guided so as to flow through the first through hole that communicates in the direction in which the laminated element extends.
In addition, the said hollow part means the hollow space part formed by laminating | stacking the 2nd through-hole of a lamination | stacking element.

  Furthermore, according to this configuration, the fluid flows out from the first through hole to the other first through hole communicating with the stacking direction, and conversely, the other first through hole communicating with the stacking direction. Since the inflow and outflow are repeated in the first through-hole communicating in a complicated manner by flowing into the first through-hole from the hole, the fluid flows more complicated and the mixing effect is increased. Also, by increasing the number of laminated elements, the cross-sectional area in the direction in which the laminated element through which the fluid flows increases, so the flow rate of the fluid circulating in the agitation tank increases and the mixing time is further increased. Can be shortened.

The second through hole forming the hollow portion is larger than the first through hole of the laminated element, and the flow resistance when the fluid flows through the hollow portion is smaller than the flow resistance when flowing through the inside of the laminated body, so the pressure loss is also small. . Therefore, even when the number of laminated elements is large, the fluid reaches the inner peripheral portion of each laminated element substantially evenly regardless of the position in the lamination direction. Therefore, the fluid flows substantially uniformly from the inner peripheral portion to the outer peripheral portion within the stacked body regardless of the position in the stacking direction.
In addition, in the conventional stirring apparatus using the stirring blade, the mixing energy can be given to the fluid mainly in a small space near the stirring blade. However, according to this configuration, the volume ratio of the mixing element in the stirring tank is increased. As a result, the mixing energy can be given to the fluid in a much larger space compared to the conventional stirring blade. Therefore, the space in the stirring tank can be used effectively, and the fluid can be mixed efficiently.

The configuration of the stirring device according to another aspect of the present invention is as follows:
In the stirring device according to the ninth technical means,
The mixing element is characterized in that an inner plate extending in the stacking direction of the stacked elements is disposed inside a hollow portion formed in the stacked body (tenth technical means).

  According to this configuration, since the mixing element has the inner plate extending in the stacking direction inside the hollow portion, a suction flow of fluid is generated in the vicinity of the surface opposite to the rotation direction of the inner plate by the rotation of the mixing element. Accordingly, a larger amount of fluid flows into the laminated body and flows through the first through-holes that are in communication to be mixed, so that the fluid is mixed more efficiently.

(5) Stirring method The stirring method according to the present invention includes:
A method of stirring fluid by a stirring device according to the ninth or tenth technical means,
The mixing element causes the fluid that has flowed into the mixing element from the second through-hole of the stacked element through the through-hole of the second plate by the self-rotating operation, and the plurality of first elements of the stacked element It flows out from the outer side part of a mixing element through a through-hole (11th technical means).

According to this method, the mixing element is rotated by the rotation of the rotating shaft, the centrifugal force acts on the fluid inside the mixing element, and the fluid is mixed while flowing through the first through hole communicating with the mixing element. It discharges from the 1st through-hole opened to a side surface. The fluid inside the stirring tank is sucked into the hollow portion by the rotation of the mixing element, and flows into the laminated body through the first through hole that opens on the inner surface of the hollow portion. Thus, the fluid is mixed.
At both ends in the stacking direction of the stacked body, the first through hole of the stacking element is closed in the stacking direction by the first plate and the second plate. Therefore, the fluid that has flowed into the laminated body is guided so as to flow through the first through hole that communicates in the direction in which the laminated element extends.
In addition, the said hollow part means the hollow space part formed by laminating | stacking the 2nd through-hole of a lamination | stacking element.

Furthermore, according to this method, the fluid flows out from the first through hole to the other first through hole communicating in the stacking direction, and conversely, the other first through hole communicating in the stacking direction. Since the inflow and outflow are repeated in the first through-hole communicating in a complicated manner by flowing into the first through-hole from the hole, the fluid flows more complicated and the mixing effect is increased. Also, by increasing the number of laminated elements, the cross-sectional area in the direction in which the laminated element through which the fluid flows increases, so the flow rate of the fluid circulating in the agitation tank increases and the mixing time is further increased. Can be shortened.
In addition, in the conventional stirring apparatus using the stirring blade, the mixing energy can be given to the fluid mainly in a small space near the stirring blade. However, according to this method, the volume ratio of the mixing element in the stirring tank is increased. As a result, the mixing energy can be given to the fluid in a much larger space compared to the conventional stirring blade. Therefore, the space in the stirring tank can be used effectively, and the fluid can be mixed efficiently.

  As described above, according to this method, the fluid in the stirring tank can be efficiently mixed by rotating the mixing element in the fluid accommodated in the stirring tank.

(6) Stirring blade The configuration of the stirring blade according to the present invention is:
A stirring blade including a mixing element according to a sixth technical means, wherein the stirring blade is supported by a rotating shaft (a twelfth technical means).

  According to this configuration, since the stirring blade includes the mixing element, when the stirring blade including the mixing element is arranged in the stirring tank, the laminate in which the flow of the fluid forms the mixing element by the rotation of the stirring blade. Since the fluid flows through the first through-hole that flows into the interior and communicates therewith, the fluid can be mixed efficiently.

(7) Stirrer The configuration of the stirrer according to another aspect of the present invention is as follows:
The stirring blade according to the twelfth technical means is arranged in the fluid in the stirring tank (13th technical means).

  According to this configuration, since the stirring blade according to the twelfth technical means is disposed in the fluid in the stirring tank, the fluid can be mixed efficiently.

(8) Stirring method A stirring method according to another aspect of the present invention includes:
A method of stirring fluid with a stirring blade according to a twelfth technical means,
Due to the rotation operation of the stirring blade, the mixing element provided in the stirring blade causes the fluid flowing into the mixing element from the second through hole of the laminated element through the through hole of the second plate, It is made to flow out from the outside part of a mixing element through a plurality of 1st penetration holes of a lamination element (14th technical means).

  According to this method, since the fluid is mixed by the stirring blade according to the twelfth technical means, the fluid flows through the mixing element provided in the stirring blade, so the fluid in the stirring tank is efficiently mixed. be able to.

  As described above, according to the mixing element, the mixing apparatus, and the mixing method according to the present invention, the mixing effect is increased because the fluid flows in a complicated manner through the communicating first through hole. Therefore, it is possible to mix a large amount of fluid by increasing the number of laminated elements. Further, the cleaning operation can be facilitated.

  In addition, according to the stirring blade, the stirring device, and the stirring method according to the present invention, the mixing effect increases because the fluid flows in a complicated manner through the communicating first through hole. Therefore, the mixing time can be shortened by increasing the number of laminated elements. Further, the cleaning operation can be facilitated. Moreover, the fluid accommodated in the stirring tank can be mixed.

(Embodiment 1 of mixing element)
FIG. 1 is a cross-sectional view showing a state in which a fluid A flows inside a mixing element 1A according to Embodiment 1, and FIG. 2 is a perspective view showing components of the mixing element 1A. FIG. 3 is a plan view showing the overlap of the first through holes 22 when the laminated element 21 is laminated with the adjacent laminated element 21.

As shown in FIGS. 1 and 2, the mixing element 1 </ b> A includes a laminated body 2 in which a plurality of (in this case, six) laminated elements 21 composed of discs are laminated, a first board 3 and a second board. 4, for example, is configured to be clamped from both sides by fixing means for four bolts 11 and nuts 12 arranged at appropriate positions.
The first plate 3 is a disc having only bolt holes. The 2nd board 4 has the circular through-hole 41 into which the fluid A flows in into the center part with the hole for volt | bolts. The first plate 3 and the second plate 4 have substantially the same outer diameter as the laminated element 21.

The laminated element 21 has a plurality of circular first through holes 22 and a circular second through hole 23 in the center. The inner diameter of the second through hole 23 is substantially the same as and substantially concentric with the inner diameter of the through hole 41 of the second plate 4. By laminating the laminated elements 21, the second through hole 23 forms a hollow portion 24.
Each first through hole 22 has substantially the same inner diameter and pitch. As shown in FIG. 3, some of the plurality of first through holes 22 are arranged so as to partially overlap the first through holes 22 of the laminated elements 21 adjacent to each other. The element 21 communicates in the extending direction. Some of the plurality of first through holes 22 are open to the inner peripheral surface and the outer peripheral surface of the laminated element 21.
The first through holes 22 of the laminated elements 21 at both ends of the laminated body are closed in the laminating direction by the first plate 3 and the second plate 4 that are arranged to face both ends of the laminated body 2. Therefore, the fluid A inside the laminated body 2 is prevented from flowing out in the laminating direction from the first through holes 22 of the laminated element 21 at both ends of the laminated body 2, and the laminated element 21 extends inside the laminated body 2. Reliable distribution in the direction.
Therefore, the fluid A is circulated in the mixing element 1A from the inner peripheral portion to the outer peripheral portion or vice versa from the outer peripheral portion to the inner peripheral portion. As described above, the fluid A is communicated between the plurality of first through holes 22 so as to be able to flow in the direction in which the laminated element 21 extends.

  In the mixing element 1A described above, for example, the fluid A flows into the hollow portion 24 via the through hole 41 of the second plate 4 by an appropriate pumping means. Next, the fluid A flows into the multilayer body 2 from the first through hole 22 of the multilayer element 21 that opens to the inner peripheral surface of the hollow portion 24. Next, the fluid A flows through the other first through hole 22 that communicates with the first through hole 22, and further flows into the first through hole 22 that communicates with the other first through hole 22. Circulate. Finally, the fluid A flows out from the inside of the multilayer body 2 through the first through hole 22 of the multilayer element 21 that opens on the outer peripheral surface of the multilayer body 2.

  As described above, the fluid A flows in a substantially radial manner from the inner peripheral portion toward the outer peripheral portion through the first through hole 22 that communicates with the inside of the laminate 2. At that time, the mixture is highly mixed by repeating dispersion, merging, inversion, turbulent flow, vortex flow, collision and the like. In contrast to the above, the fluid A may flow from the outer peripheral portion of the stacked body 2 of the stacked elements 21 and flow out from the inner peripheral portion.

Dispersion, confluence, inversion, turbulence, vortex flow, and collision are generally as follows. That is, the dispersion is the dispersion when the fluid A flows out from each first through hole 22 to the adjacent first through hole 22, and the merge is the first adjacent from the plurality of first through holes 22. The reversal of the merging due to the fluid A flowing into the through hole 22 is the reversal of the fluid A inside the first through hole 22. The turbulent flow is an irregular flow of the fluid A, and the vortex is a vortex flow generated along with a strong turbulent flow, and these flows collide with each other.

  The hollow portion 24 has a sufficient size with respect to the first through-hole 22, and the second through-hole 23 of each laminated element constituting the hollow portion 24 has substantially the same inner diameter and is substantially concentric. is there. Therefore, the flow resistance when the fluid A flows through the hollow portion 24 is smaller than the flow resistance when the fluid A flows through the laminated body 2, and the pressure loss is also small. Therefore, even when the number of laminated elements 21 is large, the fluid A reaches the inner peripheral part of each laminated element 21 almost uniformly regardless of the position in the lamination direction, and the inside of the laminated body 2 is changed from the inner peripheral part to the outer peripheral part. Flows evenly to the part.

In addition, in the first through hole 22 of the laminated element 21 whose upper surface and lower surface are in contact with the other laminated element 21 inside the mixing element 1A, the other first of the upper surface and lower surface from the first through hole 22. Therefore, the fluid is dispersed by the other first through holes 22 on the upper surface and the lower surface. Further, since the first through hole 22 flows from the other first through holes 22 on the upper surface and the lower surface, the fluid from the other first through holes 22 on the upper surface and the lower surface merges. Therefore, the mixing effect is high and the fluid A is highly mixed.
In particular, when the flow rate increases and the flow state shifts to turbulent flow, the effects of turbulent flow and vortex flow are enhanced, and the fluid mixing effect associated with the dispersion and merging is further increased. Even when the flow rate is low and the flow state is laminar, the fluid is highly mixed because it is dispersed and joined to the upper and lower surfaces.

In addition, since the laminated element 21, the first plate 3 and the second plate 4 can be disassembled into each, cleaning operations such as removal of residues and foreign matters remaining in the first through holes 22 of the laminated element 21 are easy. Can be.
Moreover, since the lamination element 21, the 1st board 3, and the 2nd board 4 can be manufactured separately, manufacture of the mixing element 1 is easy and can be manufactured cheaply.
Further, when a substantially annular plate is manufactured as the laminated element 21, a metal plate having a certain thickness, such as a punching metal, can be formed by punching, so that the mixing element 1 can be manufactured at a lower cost. Can do.

For example, the 1st through-hole 22 of the lamination | stacking element 21 is good also as polygonal shapes, such as a regular tetragon, a triangle, a hexagon, a rectangle, as shown in Fig.9 (a)-(d) not only circular. Since the opening ratio of the laminated element 21 is increased by forming the first through hole 22 in a polygonal shape, the flow resistance of the mixing element 1 can be reduced.

Further, when a substantially annular plate is manufactured as the laminated element 21 in each of the above-described mixed element embodiments, a metal plate having a certain thickness, such as a punching metal, is punched by punching or the like, and a large amount is obtained in a short time.

The inner diameter of the second through hole 23 of the laminated element 21 is substantially the same as and substantially concentric with the inner diameter of the through hole 41 of the second plate 4. By laminating the laminated elements 21, the second through hole 23 constitutes a first hollow part 24a, a second hollow part 24b, a third hollow part 24c, and a fourth hollow part 24d, which are hollow spaces. . Each hollow part 24a-24d is the hollow part 24 corresponding to each laminated body 2a-2d.

Surely in the direction of

  In the mixing apparatus 5A having the above configuration, for example, the fluid A flows from the inlet 51 by an appropriate pumping means and flows into the first hollow portion 24a. Subsequently, the fluid A flows into the first stacked body 2a from the first through hole 22 that opens in the inner peripheral surface of the first hollow portion 24a, and flows through the first through hole 22 that communicates in the outer peripheral direction. Subsequently, the fluid A flows out from the first through hole 22 opened on the outer peripheral surface of the first stacked body 2a, and flows into the first annular space 55a.

Since the laminated element 21, the first plate 3 and the second plate 4 have a simple structure, they can be made of materials such as ceramics which are difficult to manufacture with a structure such as a conventional flow guiding unit. . Therefore, the mixing element 1, the mixing device 5, the mixing method, the stirring device 6, and the stirring method can be applied to applications that require corrosion resistance and heat resistance.

  Moreover, since a large space is not required and it can be arranged in a pipe line, for example, the mixing element 1 and the mixing device 5 are installed in a place where the installation space is limited such as an exhaust gas line of a diesel vehicle. A mixing method can also be applied. In this case, when the exhaust gas and the reducing agent are mixed well, the decomposition rate of nitrogen oxides in the exhaust gas is improved. Therefore, since the concentration of nitrogen oxides in the exhaust gas is reduced, it can contribute to the improvement of the global environment.

  Moreover, the mixing element 1, the mixing apparatus 5, and the mixing method can also be applied to a catalytic reactor inlet for mixing and reacting several kinds of fluids in a chemical plant. In this case, since the concentration distribution of the fluid supplied to the catalyst layer is reduced, the reaction rate is improved, and the yield of the target product can be improved. As a result, the energy efficiency of the entire chemical plant can be improved and the generation of carbon dioxide can be reduced, which can also contribute to the improvement of the global environment.

  The embodiment disclosed above should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above-described embodiments but by the scope of claims for patent, and includes all modifications and variations within the scope and meaning equivalent to the scope of claims for patent.
